I’m using Woocommerce POS plugin from another developer and after I printed my invoice I got an error from your plugin as you can see on this image:
What should I do?
A quick workaround would be disabling WP_DEBUG_DISPLAY.
A plugin is calling the filter with an argument missing. Find out what plugin is causing the issue and let the developer fix it.
